CLOTH-MACHINE Application filed February 19, 1908.

To all whom it may concern:

Be it known that I, CHARLES GoLnsTEIN. a citizen of the United States,and a resident of the city, county, and State of New York, have inventedcertain new and useful Improvcments in Cloth-Machines, of which thetollowing is a specification.

lily improved machine is especially adapted for use in hatmanufacturing, where it is desired to cut the buckram or other stiffmaterial which constitutes the foundation of the hat, more especiallywomens hats, into lengths desirable for covering hat frames.

The object of my machine is to cut the material into desired lengths andis adjustable so that the material may be cut into any length desired,according to the size of the hat frame to be covered.

l'teretotore it has been customary to cut the material by hand withshears and throw it in heaps and when the material is thus cut, owing toits nature, it curls up and much tune is spent in straightening it outready for use. This, together with the cut ting consumes a great deal oftime and makes the handling of the material expert sivc. With myimproved machine the material first moistened and then passed to acutting knife where it is cut into lengths suitable for use. Theadjustment of the cutting mechanism is such that the material may be cutinto any desired length and many pieces of the same length may be cut.Before be material passes to the knife, it pas es over rollers whichbend it in a reverse direction to that which it was in when it was onthe roll as it came from the manufacturer. ly thus wetting and reverselybending the material before cutting it the severed pieces when they comefrom the machine will be flat, ready for use and will require nohandling for the purpose of taking out the curl.

A further object of my invention is to provide a suitable means forcarrying the first end of the material from the supply roll to thefeeding or measuring rollers.

it will be obvious that by turning off the water supply the material maybe run through dry, which is desirable in some cases.

I have shown means whereby the machine may be operated either by handand foot or by power such as steam or electricity.

Specification of Letters Patent.

Serial No. 416,683.

A detailed description of one embodiment of my invention will appearhereinafter.

In the drawings forming a part of this application, Figure 1 is a sideelevation of my improved machine, Fig. 2 is a plan view thereof, Fig. 3is an end elevation thereof, Fig. i: is a. sectional view showing thetanks in which the material is moistened, Fig. is a plan view thereof,and Fig. 6 is a side elevation of a portion of the machine showingmodifications incorporated for using hand and foot power.

T he material is furnished in rolls and in order to be used it isnecessary to cut it into various lengths ranging, generally from aquarter of a yard to a yard in length, and as the material is of a verystiff nature and has been rolled some time it will curl when out, andthe handling will be difficult. It is, however, possible to run offmaterial to any extent and other than the amounts stated above, and theparts of the machine may be adjusted accordingly. Aside from this thecutting itself is slow owing to the curling tendencies of the material.It is for these reasons that I pass the material through a moisteningdevice before it is cut.

The machine consists primarily of a frame suitable for supporting thevarious working parts of the machine. In the present instance the frameconsists of a bed 1 supported upon suitable standards 2 and at the ends,and this bed together with its component parts forms the foundation ofthe machine. At the right end of the machinc as shown in Fig. 1 l haveformed suitable supports 4-, 5, and 6 for a plurality of rolls 8, 9 and10 of the material to be cut. the rolls being superimposed one above theother.

It is to be understood that in my machine several rolls of material maybe moistened and cut sin'iultaneously and though it might be possible tomoisten the several pieces of material in the san'ie moistening tank Iprefer to run the separate pieces of material through separate tanks sothat the moistening will be sutlicient and rapid. After the materialsfrom the several rolls have passed through their separate tanks they arebrought together so as to pass through the feed or measuring rollerstogether. When the material comes from the several rolls it passes underthe respective rollers 11 which bend it in a reverse direction to thatin which it was bent or curled on the supply rolls or let offs. Thiswill, to a certain extent overcome the curling tendency of the materialthe same as if done by hand, but it is not ordinarily enough tostraighten the material so as to make it suitable for use. I thereforepass the material 8 from the top roll over an idler l2 and then into atank 15 where it is moistened as it passes through. While the materialis passing through the tank water is thrown on it from the two feedpipes 20 and 21 which have discharge apertures 24 at the top where thematerial comes, and water is supplied to the pipes through the inlets22. The tank itself consists of a trough like member 18 which preferablyhas an inclined upper edge 1.9, and the water which falls into the tankfrom the pipes is led off through. an outlet 23. The material 9 and 10which is contained on the first and second rollers is passedrespectively over the rollers or idlers l3 and 14 the same as the firstdescribed piece and through their independent tanks 16 and 17 which aresimilar in every respect to the first tank 15. The inlet 22 and theoutlet 23 are common to all the tanks. By passing the several pieces ofmaterial through individual tanks it may be moved rapidly and still beproperly moistened. As the several pieces of material leave themoistening tanks they pass over idlers 25, 26 and 27 respectively andthen over other idlers 28, 29 and 30 from which they travel to thefeeding and cutting mechamsm.

As a means for feeding the material to the cutting knife inpredetermined lengths so that a certain amount of material will be cutfrom each piece and so that the amount thus cut may be altered to suitthe requirements I provide the following. Secured upon shaft-s 31 and32, which are journaled in the frame of the machine beyond the tanks andbefore the knife, are parallel roll ers 33 and 34 placed one above theother, with their peripheries very close so as to grip the materialbetween. The shaft of the upper roller I have made movable vertically sothat the upper roller will be pressed down on the lower one by itsweight, as will be seen in Fig. 1. The several pieces of material 8, 9and 10 pass from the rollers or idlers 28, 29 and 30 between the rollers33 and 34 and by moving these rollers a predetermined amount thematerial from each feed roll will be drawn forward so that the knifewill sever a like amount from each. The rollers 33 and 34 are gearedtogether at one end by the gears 35 and 36 so that they move in unisonand the same in extent. The shaft 32 of the roller 34, in the form shownin Fig. 1, is provided with a ratchet 37 and with an arm or crank 38,which latter has a pawl 39 that engages in one direction with theratchet. Mounted on a shaft 40 which is supported by a bracket 41 011theupper part of the machine frame, is a sprocket wheel 42 and also acrank 43 which latter is connected with the crank 38 by a pitman 44. Thepitman is connected at its lower end by an adjustable pin 45 which maybe adjusted along the slot 46 in the crank 33 and its upper end isconnected to the crank 43 by a similar pin 47 which may be adjustedalong the slot 48 in the crank 4-3. In this manner the relative movementof the crank 38 by the crank 43 may be adjusted. When power is appliedto the shaft 40 through the chain 49, and sprocket 42 the crank 43 willoscillate the crank 33 and the latter through the pawl and ratchetengagement will revolve the lower roller 34, and as was explained, theextent of the revolu tion will depend on the adjustment of the pitman.As the lower roller is connected to the upper by the gears 35 and 36 themovement of the lower one will be transmitted to the upper one and thematerial, in the present illustration three thicknesses, will be drawnfrom the three supply rolls or let ofls and will be moved forwardsufiiciently for the knife to cut off the desired quantity from eachpiece of material.

Forward of the feed or measuring rollers, I provide a knife which isconstructed and operated as follows. Upright supports 50 of the frameare provided with guiding grooves 51 and between the guides or supports59 and in the grooves 51 is a reciprocating knife 52 which preferablyhas its lower or cutting edge slanting to prod uce a shearing action onthe material as it passes from the feed rollers 33 and 34 over the plate54. A. shaft 55 is journaled at 56 to the uprights 50 of the frame andexterior of these uprights and on the shaft 55 I provide two disk cams57 which are alike and have cam grooves 59 in which the two pins orbowls 58 on the opposite upper edges of the knife engage. In this waythe revolving of the cams with the shaft 55 will re ciprocate the knifeand cut the material at each movement. Any power may be applied to theshaft through the pulley 60. It will be noted that the two rollers 33and 34 and the knife 52 are sufficiently wide to take the widestmaterial that is likely to be used in the machine.

IVhen the material is presented under the knife blade it rests on aplatform which supports it during the cutting and this platform is soconstructed that when the knife completes its cutting it willautomatically throw off the material and in the machine which I haveillustrated the platform is operated by the knife blade. The platformconsists of two members 61 and 62 which when in proper position are 011a line with the material as it travels between the knife edges,

and these members are hinged at 63 and 64 respectively to the frame ofthe machine so that they may be swung downwardly and discharge thesevered pieces of material therefrom. I prefer to make the platform intwo parts and hinge them as shown because I believe it will bettersuflice to discharge the material as it is cut. F or dropping theplatform members l provide a lever action which is connected to theknife so as to work in unison therewith. It consists of a lever 65 whichis fulcrumed to the upright 50 of the frame and a link (37 connects thelever (55 with a projecting arm G8 on the platform member, the linkbeing fulcrmned respectively thereto. The inner end of the lever (35 isprovided with a. loop 69 in which a pin or bowl 70 slidably engages andwhich is carried by the loop. The bowl 70 engages in an elongated slot"(1 in the knife blade 52. It will be noted that each member of theplatform is provided with the lever mechanism just described and adescription of the one will suffice for both.

As it would consume considerable time to bring the material from the letoff rolls to the feed rollers by hand each time new rolls of materialare put on the machine I have provided a very novel and simple means forquickly accomplishing this and it is such that the ends of the severalpieces of material may be passed over their respective idlers andthrough their tanks simultaneously and bring the ends to the feedrollers together. This consists of the following. Mounted on the frameof the machine at a point near where the rollers 33 and ill come incontact I provide the three rollers 75. 76 and 77 which are onrespectire shafts T2, T3 and 74. These rollers are provided with grooves78, which, in the present showing are three in number, one at each endand one in the middle of the roller. The three rollers are alike and areso disposed that their top comes just below the paths of the respectivepieces of material. Each of the rollers is provided with bands 79 andthese are provided with pins 80 which engage in the material to carry italong. The bands 79 are continuous and pass over the idlers S1 and S2and into grooves at in the several idlers which conduct the material.The ends of the shafts on which the rollers are provided each have asprocket 87 and 88 and 89 (see Fig. 1) and a chain 86 travels over thethree sprockets, so that the three rollers are geared together. A crank90 is provided on one of the shafts. and by turning the crank all threerollers are moved in unison.

The operation of my machine is as fol lows. The rolls of material, inthe present showing three, are placed on the supporting members of theframe, at the end of the machine and their ends are passed around theseveral rollers or idlers 11, which bend the material in the reversedirection to that in which it had been previously bent. The handle orcrank 90 is turned until the pins 80 on the bands 79 are brought to theend of the machine where the rollers 11 are and the material is engagedon the pins 80. lt is preferable to engage the pins in the materialbeyond the end a distance equal to the distance of the rollers 75 etc.from the feed rollers. The material from the upper roll will be placedon the three bands of the upper set. the next piece will be engaged onthe pins of the second set and the third on the third set. The crank 90is then turned and the pins on the bands 79 are all moved forwardtogethe". carrying their respective pieces of material. The upper set ofbands will carry the upper piece of material around its idlers, throughits tank and finally to a position ready for entry between the feedrollers. In like manner the second and third sets of bands will taketheir pieces of material around their idlers and through their tanks andbring them all up to the feed rollers together. As the feed rollers gripthe material the pins 80 pass out of the material and the material isfed on by the feed rollers. The bands then remain idle until the nextrolls of material are placed in the machine. The revolving of the crank43 will oscillate the crank 38 and as the pawl 39 engages the ratchet 37the feed rollers will feed the three pieces of material under the knifeblade and the knife is timed to cut at the proper moment to cut off thematerial fed by the rollers. \Vhen the material is fed to the knife theplatform is up and remains so until the knife completes its cutting,when the extremity of the slot 71 will have engaged the pin or bowl '70.rocking it downwardly to the position shown in full lines in Fig. 3,when the levers will rock the platform members on their hinges and dropthe material off. The return of the knife returns the platform. As wasexplained the adjustment of the pitman connection with the two crankswill determine the extent. of movement of the feed rollers and in thisway govern the feed of material at each operation.

As it is not always possible to provide power for the machine I haveshown in Fig. 6 a modification of the previously described device bywhich hand and foot power may be utilized for the operation of thedevice. in this form the knife is held in its upward position by a lever92 which is connected by a link 91 therewith, and supported upon abracket 93. The weight. 94 on the end of this lever holds the knifeupwardly. Vhen it is desired to cut the material a foot lever 96 ispressed and through the bar connected with the knife the latter will beforced down to cut the material against the action of the weightedlever. In this use of the device the crank 38 is provided with a thefeed rollers.

handle 97 which is turned by hand to operate In this case the teeth ofthe ratchet may be numbered and by engaging the pawl in the toothnumbered to correspond to the number of inches the material is to be fedthe crank is turned until the pawl comes to an upright position, whenthe knife is operated to cut the material. To feed again the crank isreturned to engage with another tooth on the ratchet.

Otherwise than here described the machine for hand and foot operation isthe same as for power.
